C-Warm water heater pressure relief valve

[Ric]

I removed the pressure relief valve from my C-Warm water heater today in order to de-calcify it. Unfortunately after unscrewing the spring-loaded plunger, the needle fell out before I could note the correct orientation.

The needle can actually be refitted in either direction, but after a lot of examination I decided that the orientation in this photo is correct. With this orientation, a dimple on the end (right end in the photo) fits into the bottom of the barrel of the the valve.

Is this correct?

I could not understand the purpose of the needle - any explanation gratefully received.

Bonjour Ric,
No pic visible in your post. I have a C warm calorifier 20 litre vertical model and may be able to help. to add photos to post on this forum you need firstly to upload onto photobucket and then copy img code into post.

I deduce that you have a top loading fridge on a Jeanneau and when you knock the spring opener the lid drops and bruises your arm

We have one of those but I don't know the answer. Would be worth calling C-Warm, they are usually very helpful.

Sorry I can't help other than to suggest you reassemble it as you have described and then pressurise the system and press the release button to see if it is operating correctly.

I think you'll find this rod is the temperature part of a combined pressure and temperature relief valve. So when it warms up it pushes the plunger to relief the pressure.

Changed mine last week and threw out the old valve so can't see how mine worked!
